As part of a quality-control program, 4 batteries from a box of 17 is chosen at random for testing. In how many ways can this te

belka [17]

Answer:

This test batch can be chosen in 2380 ways

Step-by-step explanation:

The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In how many ways can this test batch be chosen?

4 batteries from a set of 17. So

$C_{17,4} = \frac{17!}{4!(17-4)!} = 2380$

This test batch can be chosen in 2380 ways

The area of a circular table is 22511 in2.

zzz [600]

Answer:

1. Radius = 84.65 in

2. Circumference = 531.65 in

3. Diameter = 169.3 in

Step-by-step explanation:

1] In order to find the area of a circle, we use the formula

Area of a circle = πr²

Where r is the radius. So substitute the value of the area of the circle in the formula, to find the radius r.

22511 = π r²

r² = 22511 ÷ π

r = $\sqrt{22511 / \pi }$

r = 84.65 in

2] Now that we found the radius, we can easily find the circumference using the formula:

Circumference of a circle = 2πr

Substitute the value of r in the formula.

Circumference = 2 × π × 84.65

Circumference = 531.87 in

3] The diameter is twice the radius, so:

diameter = r × 2

diameter = 84.65 × 2

diameter = 169.3 in
